Pneumatic valve working principle and failure analysis
The so-called pneumatic valve, specifically refers to the cylinder as an actuator, compressed air as a power source to realize the drive of the valve, in order to achieve the switch to regulate.
Advantages and disadvantages of several types of valves

Plumbing fittings have characteristics
Green building materials, plumbing fittings have the healthy quality of non-corrosion, non-scaling, non-bacteria
What are the materials of alloy elbow
Alloy elbow material is diverse, common carbon steel, manganese steel, nickel steel and so on. Alloy elbow is very widely used. Ordinary alloy elbow made of bronze is more common in the general water pipeline, but with the improvement of living standards, many of the water pipeline impact is relatively strong in the pipeline. Therefore, it is often used in high temperature water vapor transmission pipelines, water and gas pipelines. Conveying pipelines and other wear and tear consumption is more serious in the pipeline.
What is the welding process of the flange
Required equipment and tools a set of manual electric welding equipment, a handle angle grinder, an electric air hammer, a plane ruler.
Three welding techniques for stainless steel welded pipes
Stainless steel welded pipe requires deep weld penetration, does not contain oxide inclusions, the heat affected zone is as small as possible, tungsten inert gas shielded argon arc welding has a better adaptability, high weld quality, weld penetration performance is good, and its products are widely used in the chemical industry, the nuclear industry, and food and other industries.
